Litchi LabsStart a pilot
Human data partner to AI labs

We recruit, vet and manage domain specialists who produce the demonstrations, comparisons and graded evaluations your post-training team actually needs. Scoped per project, delivered in your schema, with the QA numbers attached.

01·The problem

Pretraining has already eaten the public web. What moves a frontier model now is scarce: the judgment of people who practise a field, applied to the exact tasks the model still gets wrong.

That data does not exist until someone makes it, carefully, with the people who know. Making it is the whole company.

02·The people

Specialists, not crowds.

So we go to the people who hold the expertise, and we build the project around them.

Specialists, not crowds

Every contributor is a credentialed practitioner in the domain they label: physicians, chartered accountants, litigators, research mathematicians, senior engineers. We do not route expert work to generalists.

Your rubric, our calibration

Projects start with gold-standard items we author with you. Contributors must match them before they produce, and we report agreement with every batch.

Small teams, named leads

Each engagement has one project lead who reads the batches, runs the re-briefs and is on the weekly call. You will never be handed a ticket queue.

Agent-ready by default

Our MCP server answers questions about capabilities, process and contracting, and can file an inquiry on behalf of a buyer's agent. Humans and agents get the same answers.

03·The craft

Data in the shapes post-training needs.

Every data type below is produced by credentialed practitioners, calibrated to your rubric, and delivered with QA numbers.

Expert demonstrations

SFT, distillation targets

Long-form, reference-quality responses in specialist domains, with sources and reasoning shown. Written to your style guide and length targets.

Preference and ranking data

RLHF, DPO, reward modelling

Pairwise and k-way comparisons with written rationales. Calibrated against your rubric so preferences reflect domain correctness, not surface polish.

Rubric-graded evaluations

Evals, release gating

Experts score model outputs against task-specific rubrics. Disagreement is surfaced and adjudicated, not averaged away.

Agentic trajectories and critiques

Agent training, failure analysis

Step-level annotation of tool-using runs: where the model went wrong, why, and what a competent practitioner would have done instead.

Rewrites and corrections

Error correction, refusal tuning

Experts repair model drafts to a passing standard and document each change, producing paired before/after data with change logs.

Domains

Software engineering

Backend, infra, security review, code evaluation across major languages

Mathematics and quantitative reasoning

Proof-level and competition-style problems, applied statistics

Medicine and life sciences

Clinical reasoning, pharmacology, diagnostics, medical writing

Law and compliance

Contract analysis, regulatory reasoning, common-law and Indian statutes

Finance and accounting

Financial statements, audit, tax, valuation, chartered accountants

Indian languages and multilingual

Hindi, Tamil, Telugu, Kannada, Bengali, Marathi and more, by native professionals

04·The method

Scope, pilot, calibrate, scale.

Four stages, each with a written artifact and a decision point. You can stop after the pilot.

  1. 01Week 0

    Scope

    A 45-minute call becomes a written task spec: rubric, acceptance criteria, schema, sample tasks and the gold set we will calibrate against.

  2. 02Weeks 1 to 2

    Pilot

    A small expert cohort runs a calibration round, then delivers the first batch with a QA report. Fixed scope, fixed price, no long-term commitment.

  3. 03Week 3

    Calibrate

    You review, we re-brief. Agreement with your gold set must clear the bar you set before we scale. If it does not, we fix the brief or the bench, not the numbers.

  4. 04Ongoing

    Scale

    Weekly batches in your schema, a live dashboard, a named project lead and change control for spec revisions.

05·The proof

Trust is a number we ship with every batch.

Quality is a system, not a promise. Here is the system, and the controls that keep your data yours.

Quality system

  • Vetting

    Credential verification, a domain test and paid trial tasks before anyone touches client work. Most applicants do not make it through.

  • Calibration

    Gold-standard items authored with you start every project. Contributors must match them before they produce.

  • Layered review

    Author, then senior reviewer, then an audit sample. Disagreements are adjudicated and fed back into the brief.

  • Numbers with every batch

    Inter-rater agreement, audit pass rate, rework rate and time-on-task distribution ship with each delivery.

  • Integrity controls

    Identity verification, screening for model-generated text, and a disclosure policy for any tool use the spec permits. Session monitoring where contractually required.

Security and contracting

  • NDA first

    A mutual NDA is signed before any task detail is shared with us or with contributors.

  • Per-client isolation

    Contributors are assigned to one client per domain. Prompts, data and outputs are never reused across clients.

  • Least-privilege access

    Project workspaces with scoped access, revoked on offboarding. No local downloads where your spec prohibits them.

  • Your schema, your bucket

    Delivery as JSONL or Parquet into your storage or ours. Deletion on request, confirmed in writing.

  • Clear contracting

    MSA plus SOW. Pricing per item or per expert-hour. All IP in the delivered data is assigned to you. We will complete your vendor security questionnaire.

06·The new door

Send your agent. Ours will answer.

Buyers increasingly scout vendors with agents. So our front desk is an MCP server: it answers questions about capabilities, process and contracting, and can file an inquiry on behalf of the person it represents. Same answers a human would get, for any MCP client, no credentials required.

Questions

Things buyers ask first.

How is pricing structured?
Per item or per expert-hour, quoted per project after scoping. Pilots are fixed-price. We do not publish a rate card because expert cost varies widely by domain and task length.
Is there a minimum engagement?
The two-week pilot is the minimum. There is no minimum after that; most clients move to weekly batches under an SOW.
How do you source experts?
Direct recruiting from professional networks, universities and referrals from existing contributors. Every contributor passes credential verification, a domain test and paid trial tasks.
Can we talk to the contributors directly?
Yes. Senior reviewers join calibration calls, and we can arrange office hours with contributors for complex briefs.
Do you use language models in the loop?
Only where your spec permits it, and always disclosed and logged. By default contributors write without model assistance and we screen deliveries for model-generated text.
Where is data processed?
In India by default, in scoped project workspaces. We can restrict to specific regions or to your own environment on request.
Who owns the data?
You do. All IP in delivered data is assigned to you under the SOW.
What languages do you cover?
English plus major Indian languages, including Hindi, Tamil, Telugu, Kannada, Bengali and Marathi, by native-speaking professionals. Other languages on request.
Can my AI agent work with you directly?
Yes. Our MCP server at https://litchilabs.in/api/mcp answers questions and can file an inquiry on your behalf. See https://litchilabs.in/for-agents.
